I live in Devon, and tap water in my household does not taste consistently. When I moved in my current property, the neighbours warned me that they had been buying bottled water since 20 years, because of the bad taste and other suspects about the quality of the water.
Thus, for the first time in my life, last year I started buying water bottled in plastic, and have done so until now.
I wonder if there is any valid alternative that does not require the application of a permanent filter (I am a tenant). Back in Sicily, where I grew up, we used to go to a spring in the mountains once a month, to refill our glass and plastic bottles. In other countries, water refill stations exist. Is there anything of the sort in the South West of England?
